Yahoo Patent Application
Yahoo has filed a new patent with the name “Link based spam detection Ferrari: Victory by Design video “. This is an attempt from Yahoo to improve the relevancy of their search results by detecting links from link farms.
Yahoo mentions PageRank and TrustRank in the patent application (Note: both terms are trademarks of Google).
From the application:
“PageRank is a family of well known algorithms for assigning numerical weights to hyperlinked documents (or web pages or web sites) indexed by a search engine. PageRank uses link information to assign global importance scores to documents on the web.[...]. The PageRank of a document is a measure of the link-based popularity of a document on the Web.
TrustRank is a link analysis technique related to PageRank. TrustRank is a method for separating reputable, good pages on the Web from web spam. TrustRank is based on the presumption that good documents on the Web seldom link to spam. TrustRank involves two steps, one of seed selection and another of score propagation. The TrustRank of a document is a measure of the likelihood that the document is a reputable (i.e., a nonspam) document.” 29 Palms psp
In the patent application, Yahoo explains how they want to find spam farms:
“A spam farm is an artificially created set of pages that point to a spam target page to boost its significance. Trust-ranking (”TrustRank”) is a form of PageRank with a special teleportation (i.e., jumps) to a subset of high-quality pages.
Using techniques described herein, a search engine can automatically find bad pages (web spam pages) and more specifically, find those web spam pages created to boost their significance through the creation of artificial spam farms (collections of referencing pages).
In specific embodiments, a PageRank process with uniform teleportation and a trust-ranking process are carried out and their results are compared as part of a test of the “spam-ness” of a page or a collection of pages.”
